CSIC NM042- Multifunctional microporous organo-inorganic material as sorbent for hydrogen storage, heterogeneous catalyst and molecular sieve
A Spanish research institute has patented a method for obtaining and application of the material as gas storage (hydrogen, nitrogen and volatile hydrocarbons), heterogeneous catalyst and molecular sieve. The high thermal stability, sorption capability and uniformity of the pore size make this material very interesting. The institute is looking for industrial partners for a license agreement

DESCRIPTION

Hydrogen is considered one of the best alternative fuels due to its abundance, easy synthesis, and non-polluting benign nature of its oxidation products (water), but the efficient storage is a problem. That’s why the search for new materials with a capacity of gases storage, especially, hydrogen storage is of great importance. Microporous materials are characterised by structures with micro-channels or tunnels, which are responsible for their properties. The active surface is found inside channels, and the reaction with other molecules is possible when their size and form are adequate for inside channel penetrating.

A Spanish scientific group has got a wide experience in synthesis of such new microporous materials by hydrothermal synthesis, structural characterisation and some applications as catalysts and adsorbents. The current invention presents a new material with microporous structure, based on terephthalate of trivalent metal, its synthesis method and some its applications as a material for gases storage (for example, hydrogen adsorption by the sample has a form of a type I isotherm, and a uniformity of pore size, that is equal to a size of 1-2 hydrogen molecules, facilitates the adsorption), as a catalyst, molecular sieve and adsorbent. As an example of a preferable application as a heterogeneous catalyst is an oxidation of phenylmethylsulphide to phenylmethylsulphoxide with yield of 85,8% alter 4h.

The high thermal stability and a high quantity of the hydrogen adsorbed make this material very interesting for its use for hydrogen storage.

INNOVATIVE ASPECTS

Microporous organo-inorganic material obtained in soft hydrothermal conditions (between 140-170º C) from the reaction mixture that contains a rare earth element, or transition metal, terephthalic acid and its salt

COMPETITIVE ADVANTAGES

The incorporation into the extremely novel technology of design and synthesis of the new multifunctional stable materials, which could be employed in gases (hydrogen, methane) storage, in heterogeneous catalysis, etc. The resulting product is very stable; it can be used for gas storage, particularly, for hydrogen or methane storage, as adsorbent, as heterogeneous catalyst and molecular sieve
